First of all your code is wrong, presumably you meant:

Position[#, Max[#]] &@list

Secondly, even if you you actually used the correct code you, you should 
still  provide an example showing when it does not work, not just a mere 
claim that it sometimes does not. Given the amount of information that 
you have provided the most likely hypothesis seems to me that you did 
not input what you though you did or that your list was empty to start 
with.
